I want to configure my hadoop cluster to work with kerberos. I've followedthe cdh4 security guideline in the cloudera website. After a lot ofproblems, I was finally able to start the namenode without any problems.Now when I want to start the datanode, I get the following error:

What OS packages of CDH4 are you using? And how exactly are youattempting to start your DN? Do you simply do "sudo servicehadoop-hdfs-datanode start" and get this?
